+- When a man(1) command returns no result and there was an -S
+  argument, check the -S argument against the list of valid
+  architectures and say "Unknown architecture AAA" rather than
+  "No entry for NNN in the manual" if there is no match.
+  Requires moving the lists of valid architectures out of
+  mdoc_validate.c such that they can be used by main.c.
